First of all thanks for your replay highly appreciated!
Yesterday i talk with NEC online chat,and their agent confirm the monitor is
new,just to make sure i called Thenerds.net, and give them the order number
so they can confirm its new.The guy told me the monitor is new based on
order number so guess it was not fraud,still i have to find out why the monitor
original package was replaced with awful box whitout stryrofarm at sides
or any protection on it!!!

All parts of the monitor was put in one
plastic bag so they where hiting during the transport and the monitor
is quite damaged and "drity" However what makes me fell really bad!
Is the fact i didn't recive warranty list,or any card just an user manul for
what i was told by nec agent that it include the warranty (strange)
I'm not sure that he understand me what i was asking for (my poor english)
The monitor have wuxi in its name no doubt.No receipt was included.
Items included in the package:
1.Cables
2.Spectraview II kit.
3.Adjustable Stand.
4.User Manual.
5.Monitor
Now after i found out that the monitor is new im almost sure(90%)
One more thing i wan't to know is how does USPS treat
damaged items? how does their refund system works,do they cover
the whole damage (full refund) or only % of the unit cost was insured.
Express mail ineternational,the guy who sent the unit paid 100$
So based on that i wan't to know will i recive new unit, or they will
cover the damaged lets say with 200/300 $? Please someone
explain me about USPS, refund system im desperate
Many thanks to all who answered me esspecally,MegalosSkylaki
